Keep it with an explanation of why a genuine change occurred. An unexplained replacement can conceal the very issue the review needs to resolve.
Record the decision behind the revision
List the author, date and changed responsibilities. Ask whether the employment agreement and customer instructions also changed. A consistent final file should reflect reality, with credentials connected to the actual work rather than an abandoned version of the role.
Prepare a factual description of the position, the pay and period, and the identity and qualification records the applicant relies on, and resolve any meaningful difference between the offer and any supporting letter before it is finalized. Build the file from records that existed before the immigration explanation: the executed offer or engagement, a detailed duty description, compensation terms, educational records, and any required licence. Ask the employer to write, for each required element, a single sentence naming the record that addresses it, and to put those sentences at the front rather than leaving a reviewer to infer the mapping from a folder of attachments. Bring the passport, the employer's offer and duty description written for this role rather than from a template, education or licensing records specific to the listed profession, translations where needed, and any prior travel or visa history.
